Escala em polegadas e milimetros.
Temos a escala principal em frações de polegadas e no verso em milimetros. Desta forma para verificarmos ou ajustamos a folga do eletrodo no padrão metrico devemos utilizar a escala estampada no verso, o que não chega a ser nenhum transtorno, só uma questão de acostumar com o uso do produto. Todavia como se trata de um produto comercializado em um país que adota o sistema métrico, as escalas deveriam estar invertidas.

Simple Design, Good Quality
While you can certainly use small calipers to measure spark plug gaps, this tool is an effective, inexpensive way to get the job done - plus you don’t need any battery/power. It seems like every time I go to use my caliper I need a battery lol. You just insert the gap tip in the hole and you can turn the plate until you determine you are at the right gap.
